Title: Double core spot size converter using selection region growing method and its manufacturing method
Inventor: RI TEISHAKU
IPC: G02F1/025
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a double core spot size converter used as an optical transmitting/receiving element used as an important part in an optical communication field and its manufacturing method. SOLUTION: Although the converter is provided with a double core structure which is composed of a lower passive optical waveguide, an upper passive optical waveguide and an active optical waveguide by interposing an about 0.3 μm thickness spacer, it is provided with a minus taper structure in which the thickness becomes thin as it goes near to a light radiating surface side from the active optical waveguide side and is simultaneously provided with a structure in which the composition is also changed gradually by growing the upper passive optical waveguide with selection region growth using a SAG pattern simultaneously with the active optical waveguide. Such a structure is different from a double core structure by a conventional etching method, and the method using the SAG is far advantageous to obtain the spot size converter having an excellent performance.  If only the condition of the SAG is secured, a double core SSC having a small beam divergent angle is realized with a high yield even through a simple etching process.
